Abstract
Способ получения пропиленгликоля путём взаимодействия исходного сырья, содержащего глицерин, в присутствии водорода, который включает стадии: (а) подачи потока, содержащего исходное сырьё, в первую зону выпаривания и контактирования указанного сырья с циркулирующим газом, содержащим водород, таким образом, чтобы по меньшей мере часть исходного сырья испарялась и поступала в поток циркулирующего газа; (б) подачи по меньшей мере части циркулирующего газа и испарившегося исходного сырья в первую зону реакции, содержащую катализатор, и проведения процесса при таких реакционных условиях, которые обеспечивают гидрирование и дегидратацию таким образом, что происходит конверсия большей части глицерина; (в) выделения из первой зоны реакции потока промежуточного продукта, содержащего циркулирующий газ, незначительные количества непревращённого глицерина и желаемый(ые) продукт(ы); (г) подачи потока промежуточного продукта из предыдущей зоны реакции в последнюю зону выпаривания и контактирования его с дополнительным количеством исходного сырья таким образом, что количество глицерина, примерно эквивалентное количеству, испарившемуся в предыдущей зоне реакции, испаряется и поступает в поток промежуточного продукта; (д) подачи потока со стадии (г) в последнюю зону реакции, содержащую катализатор, и проведения процесса при таких условиях реакции, которые обеспечивают гидрирование и дегидратацию таким образом, что происходит конверсия большей части глицерина; и (е) выделения из последней зоны реакции конечного потока продукта, содержащего циркулирующий газ, небольших количеств непревращённого исходного глицерина и желаемого(ых)A method for producing propylene glycol by reacting a glycerol-containing feedstock in the presence of hydrogen, which comprises the steps of: (a) feeding a feed-containing feed into the first evaporation zone and contacting said feedstock with a circulating gas containing hydrogen, so that at least at least part of the feedstock evaporated and entered the stream of circulating gas; (b) supplying at least a portion of the circulating gas and evaporated feedstock to the first reaction zone containing the catalyst, and carrying out the process under such reaction conditions that provide hydrogenation and dehydration so that most glycerol is converted; (c) isolating from the first reaction zone an intermediate product stream containing circulating gas, minor amounts of unconverted glycerol and the desired product (s); (d) feeding the intermediate product stream from the previous reaction zone to the last evaporation zone and contacting it with an additional amount of feedstock so that an amount of glycerin, approximately equivalent to the amount evaporated in the previous reaction zone, evaporates and enters the intermediate product stream; (e) feeding the stream from step (d) into the last reaction zone containing the catalyst, and carrying out the process under such reaction conditions that provide hydrogenation and dehydration in such a way that most of the glycerol is converted; and (e) isolating from the last reaction zone a final product stream containing circulating gas, small amounts of unconverted starting glycerol and the desired (s)
